wireless communication technologies

Wireless communication technologies enable devices to exchange data without physical connections by using radio waves or other electromagnetic signals. Examples include Wi-Fi, which connects devices to the internet within a local area; Bluetooth, used for short-range device pairing; and cellular networks like 4G or 5G, which provide mobile phone service over large areas. These technologies rely on transmitters and receivers to send and receive signals, allowing for flexible, portable connectivity. They are essential for everyday activities such as browsing online, making calls, streaming media, and supporting the Internet of Things (IoT).
